Solar panel



FIG. 1 is a front perspective view of a solar panel showing my new design;

FIG. 2 is a side elevational view thereof;

FIG. 3 is a rear perspective view; and

FIG. 4 is a top plan view; the bottom view being identical thereto.

The characteristic feature of my design resides in the louvred appearance of the front surface, with a dark band on each louvre element. 

The ornamental design for a solar panel, substantially as shown and described.
